Robbie Keane rescued Tottenham with a last-gasp equaliser as Sunderland saw a precious English Premier League victory wrenched from their grasp at the death.
Referee Phil Dowd was the villain for the home supporters among a crowd of 37,894 when he failed to award a penalty for Ledley King's 89th-minute challenge on Kenwyne Jones as the home side tried to kill off the game.
Their anger was compounded when the visitors broke for Darren Bent to send in a cross which Keane converted with a superb volley to snatch a point.
No-one will have been more relieved than Bent, who had earlier passed up a glorious opportunity to level in a scrappy contest.
Sunderland had taken the lead through Kieran Richardson's third-minute strike, and looked to have eased themselves seven points clear of the drop zone before Keane ruined their day.
Both clubs are now five points clear of the bottom three, but remain too close for comfort to the battle for top-flight survival.
With the game the only Premier League fixture of the afternoon, the sides sitting in 13th and 14th places in the table, separated only by goal difference, had an opportunity to ease themselves up the table.
Sunderland, the lower of the two before kick-off, got off to the perfect start when a Spurs defense perhaps feeling the effects of a sixth game inside 17 days was caught napping with just three minutes gone.
Steed Malbranque overran the ball to allow Ledley King to get in a challenge, but the resulting rebound handed Richardson the chance to surge towards goal.
His first touch took him clear of the flat-footed Jonathan Woodgate, and his finish was accomplished to give keeper Heurelho Gomes no chance.
However, the goal was to prove a rare piece of quality in a largely pedestrian opening 45 minutes.
Kenwyne Jones and Djibril Cisse kept Woodgate and King on their toes throughout, although without ever fully extending them, and it was not until injury time at the end of the first half that they created another genuine opening with Andy Reid just failing to get to Phil Bardsley's through-ball before Gomes.
Spurs were no better with only winger Aaron Lennon looking capable of breaking down a well-organized Sunderland rearguard as he gave full-back George McCartney a torrid time.
Bent only just failed to meet Lennon's driven 10th-minute cross with his forehead, and Keane could not get enough power into his effort from the same source seconds later to trouble keeper Marton Fulop.
Indeed, it was left to King to force the first notable save from the Hungarian, who started his career in England at White Hart Lane.
Richardson was penalised for a foul on Lennon and when Jermaine Jenas' shot was blocked, King pounced on the rebound from close-range to force a brave stop.
Cisse found himself in on goal within seconds of the restart and powered his way into the box from the right.
However, with Gomes closing down the angle, he blasted his shot harmlessly into the side-netting.
Spurs should have been back on terms after Bent was presented with two glorious opportunities within seconds.
Just what Dean Whitehead was trying to do when he sliced a 58th-minute clearance into the striker's path, only he will know, but he was spared the wrath of his manager and team-mates when Bent blasted his left-foot shot wastefully over the bar.
The former Charlton frontman, once a target for Sunderland, dragged a right-foot effort wide of the far post a minute later as the home side rode their luck.
Reid drilled a 62nd-minute cross across the face of goal and King was relieved to see the ball drop just wide after he had got the last touch when he and Cisse jumped for a high ball five minutes later.
Lennon saw appeals for a penalty for handball by Bardsley waved away and Keane lifted a difficult half-volley from Corluka's long ball over the bar as their side's desperation grew.
However, substitute Daryl Murphy could have secured the win for the Wearsiders with a left-foot drive which sailed just wide with 11 minutes remaining.
Tal Ben Haim made a vital block from Lennon with four minutes to go, but Keane saved the day with a minute remaining when, with the home crowd calling for a penalty for King's challenge on Jones, Spurs broke swiftly and Bent crossed for his captain to volley expertly home.
